I picked up a blue star leopard wrasse 2 days ago. He's in a QT by himself with a bowl of sand. I assume he's in the sand since there's really no way out of the tank and I can't see him. How long should I give him to come out before I worry? I haven't seen him in like 2 days. I put a few mysis in and he doesn't come out, I'm hoping he eats them when I'm not around. My yellow coris did this for almost a week but now is out all the time.
